Rheological properties of dioctyl adipate-modified
The low temperature performance of DOA modified asphalt binder was improved by 30%. The residual creep rate ratio of the plasticizer-modified asphalt binder was more than 15% higher than base
Dioctyl Adipate (DOA) - Chemical Supplier Distributor Chemceed
Dioctyl Adipate (DOA) is a colorless, odorless, transparent oily liquid that is most often used as a PVC plasticizer. DOA is compatible with a wide range of materials such as nitrocellulose, ethyl cellulose, most synthetic rubbers, cellulose acetate butyrate, PVC, chloroethylene polymer, and cellulose nitrate.
Rheological properties of dioctyl adipate-modified asphalt
The rheological characteristics analysis shows that DOA could increase the viscous components in asphalt binder. However, with the increase of plasticizer content to 3.0%, the creep rate increased by 35% and the creep stiffness decreased by 39% at 24°C. The low temperature performance of DOA modified asphalt binder was improved by 30%.
Thermal-oxidation mechanism of dioctyl adipate base oil
The results indicated that the total acid number (TAN) increased significantly because of the presence of 14% carboxylic acids and low molecular weight monoesters. The tribological properties were improved by the formation of the strongly polar carboxylic acids.
TDI addition sequence in the propellant production process
The maximum addition of DOA is 2.74% to produce a dough with an even distribution of particles with the added bonding agent.

- What is the structure of Dioctyl adipate?
- The structure of dioctyl adipate is as follows: This structure imparts several key properties to dioctyl adipate (DOA): ● (1) Low-temperature flexibility: DOA maintains flexibility even at low temperatures, ensuring optimal performance in cold environments.
- What is a good solvent for Dioctyl adipate?
- DOA is a non-polar molecule, meaning it tends to dissolve well in other non-polar solvents. Some examples of good solvents for DOA include aliphatic hydrocarbons such as hexane and heptane. The structure of dioctyl adipate is as follows: This structure imparts several key properties to dioctyl adipate (DOA):
- Is Dioctyl adipate toxic?
- Dioctyl Adipate has low toxicity, with an oral LD50 of 3000 to 6000 mg/kg in rats, and minimal irritation to skin and eyes. While DOA is considered to be non-toxic, it is important to handle it with care to avoid potential hazards.
- Is Dioctyl adipate polar or nonpolar?
- Dioctyl adipate (DOA) is an organic compound belonging to the ester class, with a chemical formula of (CH2CH2CO2C8H17)2. Its molecular structure consists of two octyl groups (C8H17) connected by a central adipate group (CH2CH2CO2). DOA is a non-polar molecule, meaning it tends to dissolve well in other non-polar solvents.
